296P/Garradd (0296P)

Type: Periodic Perihelion date: 17 September 2020 Perihelion distance (q): 1.8 Aphelion distance (Q) : 5.2 Period (years): 6.5 Eccentricity (e): 0.48 Inclination (i): 25.2 JPL orbit diagram COBS lightcurve 296P/Garradd = 2007 H3 = 2014 A1 Gordon Garradd discovered a 17th magnitude comet on images taken for the Siding Spring Survey with the 0.5-m Uppsala Schmidt on 22 April 2007. It was confirmed by N. Teamo and Sebastian Hoenig using a 0.41-m f/8 reflector at Punaauia, Tahiti. Prediscovery images from March were found in Siding Spring observations. The comet reached perihelion at 1.8 AU in mid August, and has a period of 6.5 years. The comet was recovered by an observing team at the Pierre Auger Observatory, Malargue using the 0.3m f/10 reflector on 6 January 2014. Following recovery prediscovery NEAT images from 2001 June were identified. The comet was close to the predicted time of return.
